Etymologies

from The American Heritage® Dictionary of the English Language, 4th Edition

From New Latin Testācea, order name, from Latin, neuter pl. of testāceus, covered with a shell, from testa, shell.

Examples

  • The testacean is almost the only genus that throughout all its species is non-copulative.

    The History of Animals

  • Even in the case of the testacean we speak of spawning (or pregnancy); but whereas the crustaceans may be seen coupling and laying their spawn, this is never the case with testaceans.

    The History of Animals

  • Molluscs, after pairing and copulation, lay a white spawn; and this spawn, as in the case of the testacean, gets granular in time.

    The History of Animals

  • But, we would beg to remind all such astute reasoners, of what they seem to be ignorant, namely, that sometimes diamonds are picked up from the dirtiest dung-hills, while the most beautiful of pearls are taken often from the bodies of the ugliest of testacean bivalves.
